# What determines isotopes for carbon dating

This is called the half-life—the amount of time required for one-half of a given number of atoms to disintegrate. The plot of the number of tiles as a function of the number of turns looks like this: Again, I made radioactive spheres disappear when they decayed.

This is fine, because when carbon-14 decays, it produces nitrogen-14. But you could imagine that if you knew that the sample started with 20 percent blue spheres and you knew their half-life, then you could determine the age by examining one frame from the animation.

C-14 locked in an object from several thousand years ago will decay at a certain rate.

With their knowledge of chemistry, archeologists can measure how many thousands of years old an object is.

There are a number of ways to enter into a career in studying radiocarbon dating.

Typically, a Master's Degree in chemistry is required because of the extensive lab work.

If we look at the C-14 atom one more time, we find that C-14 does not last forever.

The other method is “Relative Dating” which gives an order of events without giving an exact age (1): typically artefact typology or the study of the sequence of the evolution of fossils.
